Abstract

PURPOSE: The power source line and signal line are separated; and proper signal generating section which is made ot semiconductor is connected, while transmitter-receiver circuit is connected to signal line respectively. The signal transfer between transmitting and receiving is performed by photocoupler. Thus, dependability is increased with simple constitution.
